inbuilt string methods in python 3.10

1. Split()- Being a competitive coder, this function is one of the most used function in my coding carrier.

This is a very simple and very important at the same time. This function helps in splitting a string with

help of a delimiter.

Ex:

s = "hello there"

s.split(' ')

output: ['hello', 'there']

2. format() – This is also a very important string function. It helps us to format any string. We give some

variables in {} and specify their value at the end of the string. It helps us in creation of dynamic strings.

Ex: txt1 = "My name is {fname}, I'm {age}".format(fname = "swapnil", age = 21)

Output: My name is swapnil, I'm 21

3. upper() and lower()– These two functions helps us to convert a string into uppercase or lowercase.

Str.upper() converts a string in uppercase and str.lower() converts the string into lowercase.

Ex:

s = 'Hi i am Swapnil'

print(s.upper())

print(s.lower())

output:

HI I AM SWAPNIL

hi i am swapnil

4. find()– This is also one of the most used functions and helps us to find if a sub string is present inside

a string or not.

This function returns starting index of the substring if the substring is present, else returns -1.

Ex:

s = 'Hi i am Swapnil'

print(s.find('Swapnil'))

print(s.find('hello'))

output:

8

-1

5. replace()– This function helps us to replace any substring of a string with any desired new string. It

takes old substring which is to be replaces and new string as its parameter.

Ex:

s = 'Hi i am Swapnil'

s.replace('Hi','hello')

output:

hello i am Swapnil

6. isalpha()– This function returns true if all the charecters in a given strings consist of alphabets,

otherwise returns false.

Ex:

s = 'apple'

print(s.isalpha())

s='1'

print(s.isalpha())

output:

True

False

7. isdigit()– This function returns true if all the charecters in a given strings consist of digits, otherwise

returns false.

Ex:

s = 'apple'

print(s.isalpha())

s='1'

print(s.isalpha())

output:

False

True

8. count()– This function returns count of any substring given as a parameter in this function.

Ex:

s = 'apple'

print(s.count('p'))

Output:

2

9. endswith() and startswith()– These functions checks if the string starts or ends with a substring

given as a parameter in these functions.

Ex:

s = 'apple'

print(s.startswith('a'))

print(s.endswith('e'))

Output:

True

True

10. strip()– This function helps in removing all the extra whitespaces from any string.

Ex:

s = '              apple              '

s.strip(' ')

Output:

Apple
